Abstract:
A method for updating an operating system (OS) and a handheld electronic apparatus are provided. In the method, when an updating instruction is received by the handheld electronic apparatus, an updating procedure is executed by an updating module of firmware in the handheld electronic apparatus. The updating procedure includes steps of backing up item data in a first storage area to a second storage area, updating the OS that is installed on the first storage area, and restoring the item data from the second storage area to the first storage area after the OS is completely updated.
Abstract:
An antenna-integrated isolation cover comprises a main body, a first antenna unit, and a plurality of holes. The main body has a first side. The first antenna unit is disposed on the first side of the main body. The holes are disposed to the main body. An electronic apparatus using the antenna-integrated isolation cover is also disclosed.
Abstract:
A flexible terminal includes two flexible parts and a connecting part. Each flexible part includes an outer segment having a first end and a second end, a first bent segment having one end coupled to the first end, and an inner segment coupled to the other end of the first bent segment. The connecting part is coupled to two second ends of the outer segments. Due to the flexible arrangement of the flexible parts, the flexible parts can be flexibly deformed to fit the dimension of a fastening element. In addition, the inner segments of the flexible terminal can clip the fastening element so as to avoid the relative displacement of the flexible terminal and the fastening element during the operation.
Abstract:
A method of examining a test apparatus for a wireless network device is performed with a computer apparatus, a vector signal analyzer, and a vector signal generator and includes a signal receiving/transmitting step and a result outputting step. A transmitting signal test value and a receiving signal test value of the wireless network device test apparatus are measured by transmitting a reference signal of the vector signal generator and performing a receiving procedure of the wireless network device test apparatus and by transmitting a test signal of the wireless network device test apparatus and performing a receiving procedure of the vector signal analyzer, respectively. After the computer apparatus outputs an error of the wireless network device test apparatus and a comparison table of standard tolerance. Accordingly, the method enables self-testing to be performed and thereby dispenses with high fees charged by examination institutions for examining the test apparatus.
Abstract:
A power supply mode switching circuit and method switch between power supply modes of a power supply device dynamically based on an operating current required for operation of an electronic product, such that the power supply device supplies a supplying current corresponding to the operating current. The circuit comprises a sampling unit, an amplifying unit, a comparing unit. The circuit is disposed between the power supply device and the electronic product, samples the supplying current from the power supply device with the sampling unit, and converts the supplying current into a sampling voltage. The amplifying unit converts the sampling voltage into an amplifying voltage by voltage amplification and outputs the amplifying voltage to the comparing unit. After comparing the voltage level of a reference voltage and that of the amplifying voltage, the comparing unit generates a control signal for switching the power supple modes of the power supply device.
Abstract:
A HomePlug with a changeable top case structure includes a casing and a socket assembly. The casing has a first coupling portion therein and has an opening. The socket assembly has a second coupling portion for coupling with the first coupling portion, such that the socket assembly corresponds in position to the opening and thereby is coupled to the casing from inside and exposed from the opening. The HomePlug with a changeable top case structure is effective in dispensing with redesign and the manufacturing of a casing in its entirety, cutting die and material costs, enhancing ease of product design, and increasing assembly universality.
Abstract:
An electronic device housing internally defines a receiving space for accommodating a circuit board and electronic elements mounted on the circuit board, and has a thermal insulation layer provided on an inner surface thereof at a position corresponding to the circuit board. The thermal insulation layer provided on the inner surface of the electronic device housing not only suppresses and prevents flames produced by, for example, the spontaneous combustion of the electronic elements in the housing from spreading to and endangering the environment surrounding the electronic device, but also enables reduced product weight and manufacturing cost of the electronic device.
Abstract:
An electromagnetic shielding cover disposed on a printed circuit board having thereon an electronic component includes a lid and a frame which are coupled together to shield the electronic component from electromagnetic interference and allow the electronic component to be changed and tested easily during a rework process.
Abstract:
An electronic device supporter fixes the electronic device to a rear-view mirror base inside a vehicle and includes an adjustive support portion, a coupling portion, and an engaging portion. The adjustive support portion adjusts the position of the electronic device relative to the rear-view mirror base. The coupling portion is disposed beside the adjustive support portion and coupled to the electronic device. The engaging portion is disposed beside the adjustive support portion and engaged with the rear-view mirror base. With the electronic device supporter, not only can the electronic device be firmly installed on a rear-view mirror base inside a vehicle, but the angle of elevation, angle of depression, and position of the electronic device can be adjusted.
Abstract:
An indicator testing system for testing a plurality of indicators disposed on an electronic product and adapted to display a status includes a plurality of light sensors, a holder for holding the light sensors, and a signal processing module. The light sensors correspond in position to the indicators on the electronic product, respectively, and each generate a corresponding light testing signal whereby the signal processing module generates a brightness testing signal related to each indicator. The indicator testing system speeds up an indicator test, enhances the precision of the indicator test, and ensures the quality of the electronic product.
